Roger, this some of my policies and some of the USPS regulations. Hope it helps. Reggie

INTERNATIONAL ORDERS
It has come to my attention over the years, that there are several chip dealers and collector/traders that will not ship overseas. Of course, that is a personal call.
I do not mind shipping overseas-internationally. I do it out of courtesy to our international members and our international chippers, whether they are CC-GTCC members or not.
There are some things in my International shipping policy that you should know, and I will list them below:
• I will only ship to customers with pay pal accounts, or are willing to send cash safely through the mail* (*Please note; chips will not be sent until funds have been received by me.)
• When sending pay pal payment; please only USD (American Funds)
• I will only ship chips, other items such as dice, match books, or anything else that is NOT a chip, I will not ship; please do not even ask.
• You should understand even though I quote postage/handling rates in my order instructions, that international shipping could be a substantial amount more. I will endeavor to get as close to an exact postage quote from the USPS web site prior to mailing. Should I be incorrect on my figures I will issue a credit slip to you on your next order or ask for a balance to be added to my pay pal account.
• The newest information in reference to international mailings recently divulged to me by the USPS is that using bubble mailers will triple your cost; if it is not a uniform thickness and it is not flexible (is rigid and does not bend). Using a #10 envelope and corrugated paper with a maximum thickness of ¼ “, up to 5 chips can be mailed.
• Since, there is a special postal customs form that needs to be filled out, for each package(bubble mailer), you should know it always takes longer to mail a package internationally; (up to an hour) and you are required to go physically to a United States Post Office.
• As you can see it takes more time, and sometimes it requires more expense to do this, please know I do it out of love of our hobby. And I do not charge extra for the handling. Please always, make sure that your name and address is spelled correctly and the spaces between names and address (streets & avenues) are correct.
Thank you for reading this and I hope this makes it easier for us to communicate, ship and receive packages of those little round treasures we all so dearly love. **One more thing, I am sure there will be more information on this subject in the near future… Sincerely, Reggie **UPDATED: 9-23-2013
USPS DEFINITION OF A LARGE ENVELOPE BELOW
(*Notice there is not a picture of a bubble envelope there)
Large Envelope

Dimension Minimum* Maximum
Height 6-1/8 inches 12 inches
Length 11-1/2 inches 15 inches
Thickness 1/4 inch 3/4 inch
* Large envelopes exceed at least one of these dimensions.
For example, an envelope 10 inches long x 8 inches high x 1/4 inch thick is considered a large envelope because it exceeds the minimum height dimension.
